我十几年前爬梯时遇到一个Tower Research Capital的员工,他说高频交易strategy要有co-lo (servers need to be in the same location as exchange computers --- co-location),他们吃的是buy side large size trades。
记得哪里看到报道,为了加速New York (cash trades) and Chicago (futures trades) 之间的通讯速度,某个HFT公司买了一大块玉米地光纤取直快那么几个毫秒。很多很多 arms race。
Buy-side institutions 就得花钱,或者自己开发或者买各类交易软件服务,把大笔交易伪装成散户无序交易,避免被HFT割韭菜。
整个一个 jungle,弱肉强食。
